A method of representing a development project is presented comprising identifying a plurality of sources comprising the development project, determining whether any of the sources are required simultaneously and, if not, dynamically generating a filter graph representation of the development project utilizing a segment filter to couple a source to multiple processing threads.
Legal claims defining the scope of protection, as filed with the USPTO.
1. A method of generating a filter graph for a user-defined processing project, the method comprising: analyzing the project for multiple accesses to a single source of media content; determining that the multiple accesses cannot be combined and/or share a common processing chain; and coupling a single instance of the media source to the one or more processing chains through a software object to satisfy the multiple accesses without invoking a commensurate number of multiple instances of the media source, wherein the software object is a segment filter and further wherein the one or more processing chains comprise: a scalable, dynamically reconfigurable matrix switch having a plurality of inputs and a plurality of outputs; at least one matrix switch input being communicatively linked with a first processing chain portion; at least one other matrix switch input being communicatively linked with a second processing chain portion; the matrix switch being configured to dynamically couple one or more of the matrix switch inputs to one or more of the matrix switch outputs.
2. A method according to claim 1 , further comprising: receiving a request for content at the software object; and issuing a seek command from the software object to the media source to retrieve the media for presentation to a requesting processing chain.
3. A method according to claim 1 , wherein the method is implemented by a render engine, exposed from an operating system to a media processing system executing on a computing system.
4. A method according to claim 1 , further comprising: identifying multiple simultaneous access to the media source; and invoking a commensurate number of software objects, coupling a commensurate number of instances of the media source to processing chains to satisfy the multiple simultaneous requests.
5. A storage medium comprising a plurality of executable instructions including at least a subset of which that, when executed, implement a method according to claim 1 .
6. A computing system comprising: a storage medium having stored thereon a plurality of executable instructions; and an execution unit, coupled to the storage medium, to execute at least a subset of the plurality of executable instructions to implement a method according to claim 1 .
7. A method of generating a filter graph for a user-defined processing project, the method comprising: analyzing the project for multiple accesses to a single source of media content; determining that the multiple accesses cannot be combined and/or share a common processing chain; coupling a single instance of the media source to the multiple processing chains through a software object to satisfy the multiple accesses without invoking a commensurate number of multiple instances of the media source, wherein the software object is a segment filter; and ascertaining whether the multiple processing chains share common pre-processing attributes and, if so, interposing one or more associated filters between the single source of media content and the software object.
8. A method according to claim 7 , further comprising: receiving a request for content at the software object; and issuing a seek command from the software object to the media source to retrieve the media for presentation to a requesting processing chain.
9. A method according to claim 7 , wherein the method is implemented by a render engine, exposed from an operating system to a media processing system executing on a computing system.
10. A method according to claim 7 , further comprising: identifying multiple simultaneous access to the media source; and invoking a commensurate number of software objects, coupling a commensurate number of instances of the media source to processing chains to satisfy the multiple simultaneous requests.
11. A storage medium comprising a plurality of executable instructions including at least a subset of which that, when executed, implement a method according to claim 7 .
